Abstract

Pemangkasan pada tanaman teh merupakan salah satu rekayasa ekofisiologi yang dilakukan untuk menginisiasi pertumbuhan tunas sebagai bakal pembentukan pucuk peko. Sitokinin, salah satunya benzil amino purin (BAP), merupakan zat pengatur tumbuh yang dapat diaplikasikan untuk memacu inisiasi tunas setelah pemangkasan. Tujuan penelitian adalah mengetahui pengaruh pemangkasan dan penggunaan sitokinin terhadap pertumbuhan dan hasil tanaman teh. Penelitian dilaksanakan di Kebun Percobaan Pusat Penelitian Teh dan Kina Gambung pada ketinggian 1250 m di atas permukaan laut (dpl), mulai bulan Juni sampai Agustus 2018. Penelitian menggunakan tanaman menghasilkan (TM) klon GMB 7 berumur 7 tahun. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) yang terdiri dari 8 kombinasi perlakuan dengan 4 ulangan sehingga terdapat 32 unit percobaan, meliputi perlakuan pemangkasan bersih dan pemangkasan jambul/ajir, tinggi pemangkasan 40 cm dan 60 cm, serta konsentrasi zat pengatur tumbuh BAP. Peubah yang diamati adalah jumlah pucuk peko, jumlah pucuk burung, bobot segar dan kering pucuk. Hasil penelitian menunjukkan bahwa kombinasi dari jenis dan tinggi pangkasan dengan pemberian BAP berpengaruh terhadap jumlah pucuk peko dan pucuk burung pada pemetikan ke-3, namun tidak berpengaruh terhadap bobot segar dan kering pucuk. Perlakuan pemangkasan secara bersih ataupun jambul/ajir pada tinggi pangkas 60 cm dan diikuti pemberian BAP 60 ppm, merupakan perlakuan terbaik dalam menghasilkan jumlah pucuk peko  dan mengurangi jumlah pucuk burung.

Abstract

Cabe rawit umumnya berwarna hijau, jingga dan merah. Tiap tingkat kematangan memiliki kualitas yang berbeda. Teknologi non-destruktif visible/near infrared spectroscopy (Vis/NIRS) telah banyak digunakan untuk memprediksi kualitas secara cepat dan akurat serta tidak merusak. Penelitian bertujuan untuk mengetahui kandungan kadar air, total karotenoid dan antioksidan dua varietas buah cabai rawit dengan tingkat kematangan berbeda dan memprediksi kualitas secara non-destruktif menggunakan Vis/NIRS. Penelitian dilakukan di Laboratorium Hortikultura, Fakultas Pertanian, Universitas Padjadjaran. Penelitian disusun dalam rancangan acak lengkap (RAL) dengan 6 perlakuan yaitu varietas ‘Manik’ dan ‘Domba’, yang dipanen pada 20 hari setelah bunga mekar (HSBM), 40 HSBM dan 60 HSBM, serta diulang 5 kali. Data dianalisis dengan analisis varians (ANOVA). Hasil penelitian menunjukkan bahwa varietas ‘Manik’ and ‘Domba’ yang dipanen pada 20 HSBM memiliki kandungan kadar air dan antioksidan tertinggi sedangkan total karotenoid meningkat pada buah matang. Model kalibrasi dan uji validasi silang kadar air, total karotenoid, dan antioksidan mendapatkan nilai Rkal  ≥ 0,87 dan Rval  ≥ 0,84. Berdasarkan hasil tersebut, maka kandungan air dan antioksidan terbesar yaitu buah cabai rawit hijau sedangkan total karotenoid tertinggi pada buah cabai rawit merah. Vis/NIRS dapat digunakan untuk mendeteksi kandungan air, total karotenoid dan antioksidan pada buah cabai rawit. Generally, cayenne pepper is coloring in green, orange, and red. Each maturity level has a different quality.  A non-destructive technology, visible/near infrared spectroscopy (Vis/NIRS), has been widely used to predict the quality quickly and accurately without causing damage. The study aimed to determine water content, total carotenoids, and antioxidant of two varieties cayenne pepper with different maturity levels and to predict quality non-destructively using Vis/NIRS. The research was conducted at the Horticulture Laboratory, Agriculture Faculty, Universitas Padjadjaran. The research was arranged in a completely randomized design (CRD) with 6 treatments, namely ‘Manik’ and ‘Domba’ varieties harvested at 20 days after flowering (DAF), 40 DAF and 60 DAF, and 5 replications with analysis of variance (ANOVA). The results showed that ‘Manik’ and ‘Domba’ harvested at 20 DAF had the highest water content and antioxidant while the total carotenoids increased in ripe fruit. The calibration model and cross-validation of water content, total carotenoids, and antioxidants obtained values of Rcal 0.87 and Rval 0.84. Based on these results, the highest water and antioxidant content was green cayenne pepper, while the highest total carotenoids were in red cayenne pepper. Vis/NIRS can be used to detect water content, total carotenoids, and antioxidants in cayenne pepper.

Abstract

Enhancement of productivity of potato plants grown on poor-P soil such as Inceptisols due to application of arbuscular mycorrhizal fungi (AMF) has been acknowledged. However, whether this AMF improved the quality of potato tubers is still need further investigation. This study was conducted to evaluate the effectiveness of AMF in enhancing potato quality and determine whether the addition of compost and biochar to soil can support the productivity of this biofertilizer in enhancing the nutrient content in the tubers of potato plant. Screen house experiment was set up in factorial design with treatments were organic matter types (compost and compost plus biochar), and application of arbuscular mycorrhiza (without and with AMF consisted of Glomus sp. and Gigaspora sp.). Results of experiment showed that there was no interaction effect between organic matter and AMF on quality of potato tubers, however, the individual treatment especially AMF  increased the content of protein and lipid of potato tubers. Biochar that added to soil with compost was also increased the lipid content of potato tubers. This finding showed that AMF application in potato production grown in poor P-soil was not only increased the yield of potato, but also increased the quality of potato tubers.

Abstract

This research aimed to study the addition of ameliorant material in the soil to increase fertility rates, especially for potato plants grown at the height of 750 m above sea level. The experiments were conducted on medium plains 750 m above sea level in the Jatinangor area, Indonesia, with land type Incepticol. The composition of ameliorant consists of Cattle manure, biochar from coconut shells, and dolomite. The seeds of the potatoes used are relatively good varietal when cultivated in a medium plain. The design of the environment used is the group’s random draft repeated three times, the treatment design consists of K0: control; K1: Cattle manure 10 Mg ha-1; K2: Cattle manure 20 Mg ha-1; K3: Cattle manure 8 Mg ha-1, dolomite 1 Mg ha-1, 1 Mg ha-1 biochar; K4: Cattle manure 16 Mg ha-1, dolomite 2 Mg ha-1, 2-Mg biochar ha-1, K5: Cattle manure 8 Mg ha-1, dolomite 2 Mg ha-1; K6: Cattle manure 16 Mg ha-1, dolomite 4 Mg ha-1; K7: Cattle manure 8 Mg ha-1, biochar 2 Mg ha-1; K8: Cattle manure 16 Mg ha-1, biochar 4 Mg ha-1. Results showed that the composition and dose of ameliorant could increase the value of soil pH but have not improved the C/N ratio and absorption of phosphorus plants. The best result was obtained from the composition treatment of 16 Mg ha-1 Cattle manure, 2 Mg ha-1 dolomite, and 2 Mg ha-1 biochar. Soil pH is capable of increased by 16.83%, and the size of the potato bulbs of Class L (450-550 mm) amounted to 35, 11%, size M (350-450 mm) by 25.89%, and size S (200-350 mm) amounting to 34.37% when compared with controls.

Abstract

The quality component measurement of horticultural products becomes more important to achieve better quality products also to obtain uniform product. Recently, measurement by non-destructive methods turns out to be more needed, because consumers become more selective and demand producers to develop a quick, effective and accurate quality assessment system. Near Infrared Spectroscopy (NIRS) can measure plant contents quickly, relatively economical in a bigger scale, and importantly non-destructive. The measurement of quality components of green bitter gourd, such as firmness, water content, total soluble solid, and color, are important but have not been widely conducted. This research was conducted from June to August 2013 at Post Harvest Laboratory, Faculty of Agriculture, Padjadjaran University, Sumedang, Indonesia with PLS regression modeling method. The results show R-value and standard error of 0.91 and 0.47 for water content, 0.93 and 1.03 for firmness, and 0.95 and 0.49 for a* value of fruit color.

Abstract

Efforts to intensify oil palm (Elaeis guineensis Jacq.) are needed to increase productivity close to the actual production potential of oil palm crops. The productivity and growth of oil palm is partly controlled by the relationship between the top of the plant (the leaf) and the bottom of the plant (root). This study aims to find out the effect of root pruning and the number of fronds on the growth, production and quality of oil palm products. The research was conducted for 12 months from February 2018 to January 2019 in gardens owned by the community of Petapahan Village, Tapung District of Kampar Regency, Riau. The research was conducted experimentally using split plot design which is grouped based on different plant age (5 years, 10 years and 15 years). The main plot is the pruning of oil palm, Normal, Light, and Heavy fronds. The plot is trimming the roots of oil palm 75%, 50% and 25%. The results showed that root pruning and the number of fronds did not affect the interaction of observational premeters. Pruning the roots independently gives a noticeable influence on the content of mesocarp oil. Self-trimming of the fronds has a real effect on the total increase in oil. Plant life has a noticeable effect on enhancement, total oil, mesocarp oil and free fatty acids.
